Hcaptcha

How to Check if It’s the Enterprise Edition

🚨 Important: If you retrieve a value but website validation fails, this usually means the site is running on the Enterprise plan.

• First, try using the fields marked as Enterprise in the documentation.

• If those don’t work, reach out to the administrator for further assistance.
